DataStax, the company that commercialized the Cassandra database has added search functions to the NoSQL solution, Timothy Prickett Morgan reports for The Register. Morgan writes, “The new search functions come thanks to the welding of the open source Solr search engine, which like Cassandra is written in Java. Solr is a variant of the Lucene search engine and is an Apache project as well. It adds REST and JSON APIs to the Lucene search engine. DataStax chose Solr as its search engine to run atop the Cassandra distributed database inside of its DataStax Enterprise 2.0 release in part because it is somewhere on the order of five to six times more popular than the Apache Hadoop batch-oriented MapReduce data muncher.”
Morgan adds, “Sometimes, rather than crunching data to do filtering and correlations, you just want to search it, and Solr is fast and now can ride atop Cassandra. Companies that already like Lucene and want something that is faster and that now has no single point of failure, thanks to the replication and clustering inherent in Cassandra, can now go with DSE 2.0. In addition to Solr, DSE 2.0 has rifled around the other Apache projects and snapped inLog4j, a logging services layer, into Cassandra as well. The application logs, which help programmers debug their code, are now stored in Cassandra and are fully indexable and searchable.”
